The annexed drawing shows only by way v of example a manner of carryingout the in- 7 Q5 vention. The single figure thereof shows a longitudinalsection qf the coifee machine.

On the drawing a shows the vessel, bthe cover, -0 the movable filteringno member formed with a rod dwhich 70 forms the driving member for thefilter. The said rod d-- is adapted for sliding with-v in a guideeformed within the removable cover I) and confining. a spring 11 whichfrictionally embraces the rod d and retains 75 the member 0 in adjustedposition.

To prepare the cofiee beverage, the water is boiled within the vessel ainto which the ground coflee is poured, and the cover b is so placed inposition upon the vessel containing so the water and coffee, thefiltering member 0 having been previously adjusted to occupy a positionadjacent the top of the vessel (2. The rod d is subsequently loweredfrom the position shown in the drawing by pressure 85 exerted on theexposed end of the rod (Z and the member 0 is moved downwardly towardthe bottom of the vessel. In this manner the liquid passesthrough thefiltering member c and may be poured from the vessel into 90 cupswithout the removal of a cover I) through a passage g, while the fullyutilized solid substance of the coffee will remain trapped between thebottom of the vessel and the filter 0, the spring 71 exerting sufficient95 braking effect uponthe rod d to retain the filtering member inadjusted position.

What I claim and desire to secure by United States Letters Patent is: yA device for preparation of beverages, in-
